Ausführen von .net core als systemd-Dienst auf Ubuntu 14

das funktioniert gut,

webadmin@sandbox:/www/web/prod/prereg.example.org/prereg-sample$ dotnet restore Restoring packages for /www/web/prod/prereg.example.org/prereg-sample/WebApplication/WebApplication.csproj...

Press Ctrl+C to shut down. 

Hier ist das Ergebnis

[sandbox]/etc/systemd/system> ps aux |grep dotnet webadmin 29736 1.2 0.5 3286936 48576 pts/4 SLl+ 13:19 0:00 dotnet run webadmin 29775 1.5 0.5 21251244 42736 pts/4 SLl+ 13:19 0:00 dotnet exec /www/web/prod/prereg.example.org/prereg-sample/WebApplication/bin/Debug/netcoreapp1.1/WebApplication.dll 

Aber wenn ich dies zu systemd hinzufüge, so versuche ich, dass es sich als Linux-Dienst verhält, der zum Beispiel automatisch gestartet wird.

mit der folgenden Konfiguration

[Unit] Description=prereg application  [Service] WorkingDirectory=/www/web/prod/prereg.example.org/prereg-sample/WebApplication/bin/Debug/netcoreapp1.1/ ExecStart=/usr/bin/dotnet /www/web/prod/prereg.example.org/prereg-sample/WebApplication/bin/Debug/netcoreapp1.1/WebApplication.dll Restart=always RestartSec=10 # Restart service after 10 seconds if dotnet service crashes SyslogIdentifier=prereg-sample User=webadmin Environment=ASPNETCORE_ENVIRONMENT=Production  [Install] WantedBy=multi-user.target 

Ich bekomme diese Fehler. Haben Sie eine Idee, warum dies passiert?
